[0002] Currently, refrigerators have become an indispensable appliance in daily life, primarily serving the function of food preservation and storage, but generally not performing other functions. Related technologies offer a refrigerator capable of purifying the air in its space, comprising a cabinet and a detachable air purification device mounted on the cabinet. This air purification device has a housing independent of the cabinet, a fan, a filter, and a controller for controlling the fan and filter. The filter and fan work together to purify the air in the refrigerator's space, thus enabling the refrigerator to perform both storage and air purification functions. However, the refrigerator in this related technology is merely a simple mechanical connection; the storage and air purification functions operate completely independently, without any synergistic effect, and therefore do not contribute to saving overall energy consumption. Summary of the Invention
[0003] This application provides a refrigerator control method and a refrigerator, so as to achieve energy saving while taking into account both the refrigeration function and the air purification function of the refrigerator, and to improve the synergistic effect of the refrigeration function and the air purification function of the refrigerator.
[0004] This application provides a control method for a refrigerator. The refrigerator includes a cooling fan that operates during the refrigeration phase to form a cooling airflow path through the condenser of the refrigerator. The refrigerator also includes a purification device disposed on the air outlet side of the cooling fan. The control method includes: obtaining spatial parameters of the space where the refrigerator is located; determining a target operating time for the purification device based on the spatial parameters; controlling the purification device to start operation when the cooling fan is in the on state; and controlling the purification device to stop operation when the operating time of the purification device reaches the target operating time.
[0005] In some embodiments, the spatial parameters include area; determining the target runtime of the purification device based on the spatial parameters includes: obtaining the correspondence between area and runtime of the purification device; determining the runtime corresponding to the area of the space where the refrigerator is located as the target runtime based on the correspondence between area and runtime of the purification device; wherein, the larger the area, the longer the runtime of the corresponding purification device.
[0006] In some embodiments, obtaining the area of the space where the refrigerator is located includes: obtaining a first length of the space where the refrigerator is located in the direction of the air outlet of the cooling fan, and a second length perpendicular to the direction of the air outlet of the cooling fan; calculating the actual area of the refrigerator space based on the first length and the second length; and determining the area of the space where the refrigerator is located based on the difference between the first length and the second length and the actual area.
[0007] In some embodiments, determining the area of the space where the refrigerator is located based on the difference between the first length and the second length and the actual area includes: if the difference is less than a lower threshold, adding a compensation value to the actual area to obtain the area of the space where the refrigerator is located; and / or, if the difference is greater than or equal to an upper threshold, subtracting the compensation value from the actual area to obtain the area of the space where the refrigerator is located; wherein the compensation value is greater than 0.
[0008] In some embodiments, the space parameters further include a room type for representing the space's purpose; obtaining the correspondence between area and the operating time of the purification device includes: obtaining the correspondence between area and the operating time of the purification device corresponding to the current room type.
[0009] In some embodiments, the space parameters also include the number of people. After determining the target operating time of the purification device based on the space parameters, the control method further includes: increasing the target operating time when the number of people is 0; and / or decreasing the target operating time when the number of people is greater than 0.
[0010] In some embodiments, after obtaining the spatial parameters of the space where the refrigerator is located, the control method further includes: determining the target speed of the cooling fan based on the spatial parameters; after controlling the purification device to start operation, the control method further includes: controlling the cooling fan to run at the target speed.
[0011] In some embodiments, the spatial parameters include area; determining the target speed of the cooling fan based on the spatial parameters includes: determining the speed corresponding to the area of the space where the refrigerator is located, based on the correspondence between area and the speed of the cooling fan, as the target speed; wherein, the larger the area, the larger the corresponding speed; and / or, the spatial parameters include the length of the space where the refrigerator is located in the air outlet direction of the cooling fan; determining the speed corresponding to the current length, based on the correspondence between length and the speed of the cooling fan, as the target speed; wherein, the larger the length, the larger the corresponding speed.
[0012] In some embodiments, the control method further includes: obtaining the estimated duration of the current cooling phase of the refrigerator; and controlling the cooling fan to increase its speed when the target operating time exceeds the estimated duration.

This facilitates the synergistic effect of cooling and air purification, thus saving energy. On the other hand, the actual spatial parameters of the space where the refrigerator is located can accurately reflect the current purification needs of the space. Controlling the operating time of the purification device accordingly allows for adaptive adjustments to the purification process based on actual purification requirements, improving the accuracy of the purification process.

[0022] 10: Refrigerator; 100: Purification device; 101: Compressor; 102: Condenser; 103: Cooling fan. Detailed Implementation
[0023] Exemplary embodiments will now be described in detail, examples of which are illustrated in the accompanying drawings.
[0024] Combination Figures 1 to 3As shown, this application embodiment provides a refrigerator 10, including a refrigerant circulation system and a cooling fan 103. The refrigerant circulation system includes a refrigerant circulation loop consisting of a compressor 101, a condenser 102, a throttling device, and an evaporator. The cooling fan 103, when open, forms a cooling airflow path through the condenser 102 of the refrigerator 10, thus dissipating heat from the condenser 102. In some embodiments, the refrigerator 10 is a built-in refrigerator 10, and the cooling fan 103 is disposed at the bottom of the refrigerator 10, forming a cooling airflow path through the condenser 102. Figure 4 The heat dissipation airflow shown achieves bottom heat dissipation.
[0025] The refrigerator 10 operates in two phases: a cooling phase and a non-cooling phase. During the cooling phase, the compressor 101 of the refrigerator 10 is running, allowing refrigerant to circulate in the refrigerant loop and exchange heat to achieve cooling. The non-cooling phase is the period between two cooling phases when the compressor 101 stops running. The cooling fan 103 is switched on and off according to the changes in the refrigerator 10's operating phase, serving a cooling function when the refrigerator 10 is in the cooling phase.
[0026] The refrigerator 10 also includes a purification device 100, which is located on the air outlet side of the cooling fan 103. Here, "air outlet side" refers to the airflow path of the cooling fan 103, and is not limited to a fixed location. Thus, when both the purification device 100 and the cooling fan 103 are turned on, the air outlet from the cooling fan 103 can be purified, thereby purifying the air in the space where the refrigerator 10 is located.
[0027] In some embodiments, the purification device 100 is a filter for filtering the gas flowing through it. In some embodiments, the purification device 100 is used to release oxidizing active particles in the start-up state, and the purification device 100 is blown into the environment where the refrigerator 10 is located by the air path, thereby achieving a purification effect.
[0028] The refrigerator 10 provided in this application embodiment also includes a processor, which is electrically connected to the compressor 101, the cooling fan 103 and the purification device 100 described above, and is used to execute the refrigerator control method described below.
[0029] Corresponding to the refrigerator mentioned above, combined with Figure 5 As shown, this application provides a refrigerator control method, including steps S11 to S14.
[0030] Step S11: Obtain the spatial parameters of the space where the refrigerator is located.
[0031] Step S12: Determine the target operating time of the purification device based on the space parameters.
[0032] Step S13: With the cooling fan on, control the purification device to start operation.
[0033] Step S14: When the operating time of the purification device reaches the target operating time, control the purification device to stop operating.
[0034] Specifically, during implementation, after the purification device is started, its operating time is monitored. In some embodiments, if the operating time is less than the target operating time and the cooling fan remains on, the cooling fan continues to run. If the cooling fan stops operating after the target operating time, the purification device pauses operation until the cooling fan is turned on again. This ensures that the purification device always operates with the cooling fan on, which is beneficial for effective purification.
[0035] The refrigerator control method provided in this application determines the target operating time of the purification device based on the spatial parameters of the space where the refrigerator is located, thereby controlling the purification function. On one hand, the existing cooling fan of the refrigerator works in conjunction with the newly added purification device to achieve the purification function, eliminating the need to control a separate fan to operate when the refrigerator is in cooling mode. This facilitates the synergistic effect of cooling and air purification, thus saving energy. On the other hand, the actual spatial parameters of the space where the refrigerator is located can accurately reflect the current purification needs of the space. Controlling the operating time of the purification device accordingly allows for adaptive adjustments to the purification process based on actual purification requirements, improving the accuracy of the purification process. This effectively avoids unnecessary operation of the purification device and cooling fan, thereby achieving energy savings.
[0036] During implementation, at least a portion of the above control method begins operation in response to a purification mode activation command. Specifically, depending on the settings, in response to the purification mode activation command, steps S11, S12, or S13 are executed. In some embodiments, the purification mode activation command is directly input by the user via an input device. In some embodiments, the purification mode activation command is determined by: obtaining the concentration of polluting gas in the space where the refrigerator is located; and issuing a purification mode activation command when the concentration of polluting gas is greater than or equal to a set concentration threshold, thereby achieving automatic activation control of the purification mode. Here, the concentration of polluting gas in the space where the refrigerator is located can be determined by a gas sensor installed in the refrigerator or in the space where the refrigerator is located. In some embodiments, the gas sensor is used to detect polluting gases such as ammonia and hydrogen sulfide.
[0037] In some embodiments, the spatial parameter includes area. The space where the refrigerator is located is a cube, and the area is the base area of the cube. Determining the target runtime of the purification device based on the spatial parameter includes: obtaining the correspondence between area and the runtime of the purification device; and determining the runtime corresponding to the area of the current space where the refrigerator is located, as the target runtime, based on the correspondence between area and runtime of the purification device. The larger the area, the longer the runtime of the corresponding purification device. Different spaces of different sizes have different purification requirements, and the purification requirements increase with the increase of the space area. Therefore, when the space where the air conditioner is located has a large area, controlling the purification device to run for a longer duration is beneficial to optimizing the purification effect. In implementation, the correspondence between area and runtime of the purification device can be a preset many-to-one or one-to-one mapping relationship, that is, a runtime corresponding to an area or an area range is preset, and the runtime is directly called by the mapping relationship to determine the runtime corresponding to the current area. The area and runtime of the purification device can also be a preset formula, through which the runtime corresponding to the current area can be calculated. In this formula, area and runtime are positively correlated.
[0038] Specifically, in some embodiments, the area of the space where the refrigerator is located is obtained by the user directly inputting the actual area through an input device. Alternatively, the user inputs a first length of the space where the refrigerator is located in the direction of the cooling fan's airflow and a second length perpendicular to the direction of the cooling fan's airflow through an input device, and calculates the actual area of the refrigerator space based on the first and second lengths. This allows for a relatively accurate determination of the area of the space where the refrigerator is located without complex operations, which helps improve the accuracy of the target operating time determined based on the area. In some embodiments, considering that even with the same area, the actual length and width of the space can affect the purification effect, the area of the refrigerator space is further determined by combining the length of the space with the actual area of the refrigerator. Specifically, obtaining the area of the space where the refrigerator is located includes: obtaining the first length of the space where the refrigerator is located in the direction of the cooling fan's airflow and the second length perpendicular to the direction of the cooling fan's airflow; calculating the actual area of the refrigerator space based on the first and second lengths; and determining the area of the refrigerator space based on the difference between the first and second lengths and the actual area. In this way, by measuring the difference between the first length of the space where the refrigerator is located in the direction of the cooling fan's airflow and the second length perpendicular to the airflow direction, the actual situation of the space where the refrigerator is located can be more accurately reflected. Adjusting based on the actual area to determine the area used to determine the final operating time of the purification device helps improve the accuracy of this area, thereby optimizing the accuracy of the final determined operating time of the purification device, and ultimately improving the purification effect.
[0039] In some embodiments, determining the area of the space where the refrigerator is located based on the difference between the first length and the second length and the actual area includes: if the difference is less than a lower threshold, adding a compensation value to the actual area as the area of the space where the refrigerator is located. The compensation value is greater than 0. Due to the continuous airflow from the cooling fan, the gas used for purification flows more easily in the direction of the cooling fan's airflow, while the flow is slower in the direction perpendicular to the cooling fan's airflow. If the difference between the first length and the second length is less than the lower threshold, it indicates that the first length of the space where the refrigerator is located is smaller and the second length is larger in the direction of the cooling fan's airflow, requiring more time for the gas to diffuse in the second direction. In this case, increasing the area compensation value increases the operating time of the purification device corresponding to the area, which is beneficial for the gas used for purification to diffuse more fully in the direction perpendicular to the cooling fan's airflow, achieving greater coverage of the space and thus optimizing the purification effect.
[0040] In some embodiments, determining the area of the space where the refrigerator is located based on the difference between the first length and the second length and the actual area includes: if the difference is greater than or equal to an upper limit threshold, subtracting a compensation value from the actual area to obtain the area of the space where the refrigerator is located. The compensation value is greater than 0. Based on the foregoing analysis, considering that the gas used for purification is more easily circulated in the direction of the cooling fan, when the difference between the first length and the second length is greater than or equal to the upper limit threshold (i.e., the first length is larger and the second length is smaller), the gas can complete diffusion in the second direction in a shorter time. Subtracting the area compensation value in this case shortens the operating time of the purification device corresponding to the area, achieving spatial coverage while avoiding excessively long operating times for the purification device, thus balancing purification effectiveness and energy saving.
[0041] Furthermore, in the process of determining the area of the space where the refrigerator is located based on the difference between the first length and the second length and the actual area, only one determination process is required. This can improve the accuracy of the purification device's operation and avoid the need for multiple determinations or adjustments to the running time, thus saving computing power.
[0042] In some embodiments, the space parameters also include room type to represent the space's purpose. Obtaining the correspondence between area and purification device runtime includes obtaining the correspondence between area and purification device runtime corresponding to the current room type. In this case, the space parameters include area and room type. Considering that air purification needs may differ for different room types, combining room type and space area to determine the purification device runtime helps improve the accuracy of the final determined purification time, thereby optimizing the air purification effect on the current space. During implementation, the correspondence between room type, area, and purification device runtime can be directly set. After the user inputs the room type via an input device, the required runtime is retrieved based on this correspondence. For example, when the room type is kitchen, the air purification demand is often greater than when the room type is dining room or living room. Therefore, when the room type is kitchen, the purification device runtime is greater for the same area compared to a dining room or living room. The specific values in the correspondence are not further limited here.
[0043] In some embodiments, the spatial parameters include room type, which indicates the purpose of the space. Determining the target runtime of the purification device based on the spatial parameters includes: obtaining the correspondence between room type and the runtime of the purification device; and determining the runtime corresponding to the room type of the space where the refrigerator is currently located, as the target runtime, based on the correspondence between room type and the runtime of the purification device. Another method for determining the target runtime is provided here, in which the spatial parameters include room type. The room type spatial parameter reflects the different air purification needs under different room types. Determining the target runtime based on the room type ensures that the final determined target runtime meets the current air purification needs, thereby ensuring the accuracy of the purification device's operation and optimizing the air purification effect.
[0044] In some embodiments, the space parameters also include the number of people. After determining the target operating time of the purification device based on the space parameters, the target operating time is further adjusted according to the number of people. Specifically, when the number of people is 0, the target operating time is increased; and / or, when the number of people is greater than 0, the target operating time is decreased. The operation of the purification function is often detrimental to optimizing the user experience, especially when the purification device is used to release oxidizing active particles. There is a risk that users staying near the refrigerator may feel uncomfortable due to the high concentration of oxidizing active particles near the refrigerator. Therefore, appropriately reducing the target operating time when there are users in the space where the refrigerator is located helps to reduce the impact of the purification device's operation on the user experience.
[0045] In some embodiments, the spatial parameters include a first length of the space where the refrigerator is located in the direction of the cooling fan's airflow, and a second length perpendicular to the direction of the cooling fan's airflow. After determining the target operating time of the purification device based on the spatial parameters, the method further includes: calculating the difference between the first length and the second length; and increasing the target operating time if the difference is greater than or equal to an upper limit threshold. A difference between the first length and the second length greater than or equal to the upper limit threshold indicates that the current space has a large length-to-width difference, which is unfavorable for the propagation of purified air within the space. Therefore, appropriately extending the target operating time is beneficial for optimizing the purification effect on the space.
[0046] In some embodiments, after obtaining the spatial parameters of the space where the refrigerator is located, the control method further includes: determining the target rotation speed of the cooling fan based on the spatial parameters. After controlling the purification device to start operation, the control method further includes: controlling the cooling fan to operate at the target rotation speed. That is, combining Figure 6 As shown, the control method of the refrigerator includes steps S21 to S24.
[0047] Step S21: In response to the purification mode activation command, obtain the spatial parameters of the space where the refrigerator is located.
[0048] Step S22: Determine the target operating time of the purification device and the target rotation speed of the cooling fan based on the space parameters.
[0049] Step S23: With the cooling fan on, control the purification device to start running and control the cooling fan to run at the target speed.
[0050] Step S24: When the purification device reaches the target operating time, control the purification device to stop operating. Also, when the purification device reaches the target operating time, control the cooling fan to return to its original speed, and then control the cooling fan to operate according to the current cooling stage of the refrigerator.
[0051] In this way, the purification process can be controlled from both the running time of the purification device and the speed of the cooling fan, which helps to further improve the accuracy of the purification function and optimize the purification effect.
[0052] Specifically, in some embodiments, the spatial parameters include area. Determining the target rotational speed of the cooling fan based on the spatial parameters includes: determining the rotational speed corresponding to the area of the space where the refrigerator is located, based on the correspondence between area and the rotational speed of the cooling fan, as the target rotational speed; wherein, the larger the area, the larger the target rotational speed. When the area of the space where the refrigerator is located is large, setting a larger target rotational speed is beneficial for blowing purified air to a greater distance, thereby achieving purification of a larger area within the space and optimizing the overall purification effect.
[0053] In some embodiments, the spatial parameters include the length of the space where the refrigerator is located in the direction of the cooling fan's airflow. Based on the correspondence between the length and the rotational speed of the cooling fan, the rotational speed corresponding to the current length is determined as the target rotational speed. The larger the length, the higher the corresponding target rotational speed. When the length in the direction of the cooling fan's airflow is large, setting a larger target rotational speed helps to blow purified air a greater distance, thereby achieving purification of a larger area within the space and optimizing the overall purification effect.
[0054] In some embodiments, the refrigerator control method further includes: obtaining the estimated duration of the current cooling phase of the refrigerator; and controlling the cooling fan to increase its rotation speed when the target operating time exceeds the estimated duration. Specifically, the estimated duration of the current cooling phase is the duration before entering the non-cooling phase, which can be determined based on the refrigerator's historical operating data or the current temperature inside the cooling compartment. Specifically, the refrigerator's historical operating data refers to the duration of the refrigerator's cooling phase over a historical period. Based on the duration of the refrigerator's cooling phase in the historical operating data and the elapsed duration of the current cooling phase, the remaining duration of the cooling phase is determined, and this remaining duration is used as the estimated duration of the cooling phase. Based on the current temperature inside the cooling compartment, the time required to lower the current temperature to the target temperature can be calculated, and this time is the estimated duration. If the target operating time exceeds the estimated duration, it indicates that the purification process cannot be completed within the currently operating cooling phase. Therefore, the purification efficiency is improved by increasing the rotation speed of the cooling fan, thereby optimizing the purification effect.
